[Olsr-dev] Multi-Topology Routing for OLSR

Hello all,
I already brought this topic up in the OLSR-Users list, but I think the development list is a more appropriate venue.

Basically what I'm interested in is what RFC 4915 provides for OSPF: a way to define topologies as subsets of the "physical" topology and calculate independent routing tables for each of these subset topologies.

Using the policy based routing tool chest would allow the selection of the routing table and those the topology for packets based on configurable markers.

Is there somebody besides me interested in this?
Are you aware of an existing implementation (not necessarily in olsr.org)?
What needs to be done in olsrd to make this reality?

Here are my thoughts:HELLO, TC and probably MID need changes to carry the topology-id with the link information.
The internal link state databases need to be extended.
SPF calculation has to be done for each known topology.

Anything I'm missing?

Thanks in advance and kind regards
